HKUST-1, yomwe imatchedwanso MOF-199, ndi chipangizo chamakono cha Metal Organic Framework (MOF) chomwe chaphunziridwa kwambiri chifukwa cha mphamvu zake zochititsa chidwi za kutsatsa komanso kulekanitsa gasi. Mapangidwe ake amatanthauzidwa ndi kuphatikiza kwa zida zachitsulo za dimeric zomangidwa ndi ligand benzene-1,3,5-tricarboxylate (BTC), okhala ndi ayoni amkuwa (Cu).2+) pachimake chake, kumapereka dongosolo lolimba la kuyanjana kwa mamolekyu.
Kaphatikizidwe katsopano ka HKUST-1 kwapangitsa kuti pakhale mawonekedwe a monolithic omwe amapikisana ndi CO.2adsorption magwiridwe achikhalidwe ufa. Kupita patsogolo kumeneku n'kofunika kwambiri kwa mafakitale omwe akufuna njira zothetsera mpweya wowonjezera kutentha, mogwirizana ndi zoyesayesa zapadziko lonse zolimbana ndi kusintha kwa nyengo.
Kuphatikizika kwa zakumwa za ma ionic mu chimango cha HKUST-1 kwakhala chiwongola dzanja chachikulu, kupatsa MOF kukhala ndi kuthekera kowonjezera kutsatsa kwamadzi. Izi ndizothandiza makamaka pakubwezeretsa kutentha kwa zinyalala, pomwe kutsatsa kosankha ndikutulutsa madzi kumatha kuwongolera mphamvu zonse.
Kukhazikika kwachinyontho kwakulitsidwanso kudzera mu kutulutsa kwa HKUST-1 ndi ma polima a hydrophobic. Njirayi sikuti imangosunga kukhulupirika kwa crystalline ya MOF komanso imakulitsa mphamvu yake pakulekanitsa gasi, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo onyowa kapena achinyezi.
Njira zamakono zowerengera, monga chiphunzitso cha density functional, zakhala zikugwiritsidwa ntchito pofufuza za vibrational properties za HKUST-1. Maphunzirowa akuwunikira machitidwe ake odalira ma spin, omwe ndi ofunikira kuti akwaniritse bwino ntchito zake zamaukadaulo osiyanasiyana olekanitsa gasi.
Kaphatikizidwe ka maginito nanocomposites omwe amaphatikiza HKUST-1 watsegula njira zatsopano zothanirana ndi chilengedwe. Zophatikizika izi zawonetsa kutsatsa kwapadera kwa zoipitsa monga methylene blue ndi CO.2, kuwonetsa kugwiritsidwa ntchito kwakukulu kwa MOF pakuyeretsa chilengedwe.
Mwathupi, HKUST-1 imadziwika ndi kukula kwa tinthu kuyambira 100 mpaka 1000 nm ndi malo enaake opitilira 1000 ㎡/g. Kukula kwake kwa pore, kugwera mkati mwa 0.3 mpaka 0.5 nm osiyanasiyana, kumathandizira kusanthula kwachindunji kwa ma cell, ndikupangitsa kuti ikhale yosankha kwambiri njira zolekanitsa mpweya.
Kusinthasintha komanso kupititsa patsogolo kwa HKUST-1 kwayiyika ngati chinthu chodziwika bwino pamafakitale ambiri. Kusinthika kwake, kuphatikiza kafukufuku ndi chitukuko chopitilira, zimatsimikizira kuti HKUST-1 ipitilira kukhala mwala wapangodya pothana ndi zovuta zamasiku ano, makamaka pankhani yosamalira zachilengedwe komanso kugwiritsa ntchito mphamvu zamagetsi.
